Getting state of Dialog objects

How can I get the state of check/radio boxes in dialogs???
I know I can use GetDlgItemText() (i think) for the caption/text, but I dunno what to use for the state.

Also, does anyone know a good site with tutorials on how to use controls in win32 programming??

Thanks

EDIT: Almost forgot, I have a small dialog based app. The dialog was created using the resource editor. How can I set the Min/Max/Current Value for a Progress Bar control?? I was thinking about SendMessage but I don't know how to get the hWnd of the Bar... Please Help
